| 2.1.4 | Network congestion
Technology advances are producing faster and more intelligent desktop computers and workstations. The combination of more powerful computers/workstations and network-intensive applications has created a need for network capacity, or bandwidth, that is much greater than the 10 Mbps that is available on shared Ethernet/802.3 LANs. Today's networks are experiencing an increase in the transmission of large graphics files, images, full-motion video, and multimedia applications, as well as an increase in the number of users on a network. All these factors place an even greater strain on Ethernet's 10-Mbps bandwidth. As more people utilize a network to share large files, access file servers, and connect to the Internet, network congestion occurs. This can result in slower response times, longer file transfers, and network users becoming less productive due to network delays. To relieve network congestion, more bandwidth is needed or the available bandwidth must be used more efficiently. The methods used to implement these solutions are discussed later in the chapter.
